ABSTRACT The basic concept and operation of subsonic wind tunnel was demonstrated in this experiment by conducting airfoil drag analysis on a NACA 0015 airfoil. The small subsonic wind tunnel along with apparatus such as‚ the manometer rake‚ the inclined manometer and the pitot - static tube were used with different baffle settings to record varying pressure readings. To achieve this objective‚ some assumptions were made for the lower range of subsonic flow to simplify the overall analysis. From

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

Abstract This is the second part of the assessment for this module‚ I required to choose the one of the PPP in Hong Kong‚ Western Harbour Tunnel (WHT) which to analysis and critical evaluate its management system. The Western Harbour Tunnel (WHT) opened for public traffic on 30 April 1997‚ WHT not only does WHT reduce cross-harbour traffic congestion; it also stands out as the largest single transportation project in Hong Kong ever undertaken by the private sector. Firstly in the assessment‚ I

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first
